part -2 - wind turbine and solar panel installation explained

[slicknickverbs]

its not quite clear to me why you need 2 boxes (1 being a back-up)

[srockriver]

Which two boxes are you referring to?

[slicknickverbs]

@srockriver The circuit breaker boxes or breaker panels or electrical boxes ... i don't know what they're called. You have one as a "back up"?? Can't one main panel handle the all electricity? Why can't you simply connect to the main electrical line (from the power company) going into your existing panel.

[slicknickverbs]

@slicknickverbs Oh I just went back a watched again, I missed where u said u don't run the big loads in a power outage. Will u rewire now that u have more batteries?

[srockriver]

I will never rewire, I don't think. Because I would not be able to use any power I make if the Power company grid goes down. As I explained a few responses ago. I would need more panels/turbine to get enough power to sustain running heavy load stuff. If I did get more panels then I would just move heavy load circuits over to the backup panel. If I kept doing that, then eventually I would be totally "OFF GRID"

[srockriver]

Great point.

some folks do "only" connect to one panel. In that case, there is no backup panel. Everything would be on the "main" panel as you said.

There is one catch to having only one "main" panel.

In the one panel configuration, your inverters must disconnect completely from the grid (within milliseconds" in the event that the power company has an outage. In this case, when the inverters disconnect you can't use any power from the inverters (because they must disconnect (ieee standards).

@srockriver

[srockriver]

In this situation, the power company grid is down, you can't use power from the inverters, therefore you have no power at all because inverters have disconnected)

[srockriver]

In my configuration, when the power company grid goes down, since all my other circuits are connected to the backup panel, I can stil run the well pump, cook/bake meals, use microwave, run power tools, lights, Washing machine, plug in cooker, skillet, oven, welding machine, radios, direct tv, internet, all the bare necessities when everyone else is powerless and must wait on power company restoration.

[srockriver]

That is why I have the backup panel !. Now remember, in the event that the power co does go down, and the inverters are still powering the backup panel as I discussed earlier, everything on the main panel is dead and can't be used until the Power co restores power. FORTUNATELY, the only things that are on the MAIN panel are electric dryer and heat pumps, conventional electric stove.

[slicknickverbs]

Ok im getting this, thanks so much..... So why do you two inverters?

[srockriver]

I needed tow inverters so I could run things that need 240 volts. Specifically my well pump and air conditioner blower unit. Note** I do not power the heat pump as I said before but I do power the blower unit in the evaporator coil. This way I can circulate my heat from the wood stove throughout the house by turning the fan to "ON" on my thermostat.

ground fault breaker should not be used with a negative grounded system. you should use one or the other.

[srockriver]

Your idea would not pass the Natonal Electrical code. This is a North Carolina Inpected and approved system by the Chatham county Electrical Inspections Department.
